I'v been using vb.net to learn programming and have be using it for a year, but socket programming is completely new to me, with that in mind:

so I have two program which use the tcplistener, and tcpclient to talk to one another.

when they both run and I enter my ip and proper port numbers they recognise each other and can pass messages to one another, however when I place my client-side program onto another network segment it cannot seem to make the connection.

I believe the problem may be oriented around perhaps not entering a subnet with which to help locate my computer...?

(Also the firewalls are both off on each computer as well)
